Radiator for 320w+ TEC

[nkcd]

beside the small 2x120mm heatercore, what other size of radiator would be good to cool a 320w TEC? I'm looking into these oil cooler that's 4 passes (size of a BIXIII) to a larger size of 6-8 passes (6x80mm to 6x120mm - twice BIXIII) size.

If I'm to use the larger 8 passes (that can fit 6x120mm) size, can I use them passively or it has to be active?

These are alu tubings and alu fins (copper @ ends of loops), comes with 3/8 or 1/2 fittings. Good for TEC setup :)

Bip3 should do fine. Active for tec's, no passive there. Alu fins arent as good as copper fins.

[nkcd]

a BIP3 has alu tubes and fins right? Do you know how many passes does it have? If I'm to use an oil cooler that's bigger and better than the BIX3 then I should be fine with 320wTEC and 176wTEC for the CPU and GPU. Also, do you suggest that I do 2 individual loops with 2 Rads or 2 loops to 1 rad?

BIP3 is a dual-pass copper fin/copper tube radiator.

Interesting, so if I'm to use those 4-8 passes Alu oil coolers, I should be fine as well since it has more surface area and they'd be good enough to compensate for the differences between the Cu and Alu performances?

Oil coolers generally work allot worse than a heater core.

They are designed for a very different application than a heater core.

That said get one big enough and it will still work fine.

Do you understand the wattage a 320watt TEC will put out?

No way on earth you will EVER get good temps passive cooling with that sort of wattage.

Al wont perform loads worse than copper.
Main disadvantage with Alu is that is corrodes if its in contact with ionised water.
A rad with copper tubes and alu fins will work fine IMO. (worse than all copper, but not much worse)

I'm looking into these Flex-a-lite coolers. Their designs are pretty simple like the rads, so I figured that a 6-8 passes 6x120mm (1 side) would perform better than two small heatercores.. They do have 2 versions: one is alu tubings with alu fins, and the other is Cu tubings and Alu fins. I'm trying to find the 2nd one. I'll be checking them out so hopefully things will be as I wanted. :)

At that sort of size I think it will work ok.

But if you allready have one heater core adding a second might be cheaper and more effective in the long run.

There are reviews about the net of oil coolers as wetercooling rads.
Performance for size was allways quite a bit worse than a heatercore.

How much do these things cost? (the copper tubed one)

[nkcd]

I've yet to find the copper tubing ones. I was thinking of the dual coolers in push and pull condition and wondering if it works better than the BIXII series.

so I figured
Honestly, just reread what we've all said.
And push pull sucks.
